If the duo2 documentation may say +/- 40deg, I think they made a mistake, I'm sure they meant 40deg total.
The Novak ballistic is similar to the Duo2 in timing adjustment and markings. There documentation claims +\- 20deg.
Here is the Duo2 documentation from Epic.
The DUO 2 ROAR spec motors have been updated
for increased performance. They still feature the ability
to work with older sensorless speed controls and
the newest sensored speed controls.
Neo 2 magnets., Heavy duty ball bearings. 3 screw
adjustable infinite timing. + 40 / -40
Meets ROAR/IFMAR specs
Team EPIC is the first brushless motor manufacturer to offer a dyno tested brushless motor. What this means for the dealer and racer is that every Duo2 motor that leaves our factory has been tested and meets performance specs. This also gives the racer data from motor to motor to better judge gearing as we all know by now that brushless motors need as much care as brushed motors to keep them from melting down.
All Duo 2 motors are tested with the maximum timing setting which insures that the specs from motor to motor are comparable. Doing the testing this way takes any adjustable timing differences out of the equation.
The results for each motor are right on the box, (rpm, watts, efficiency & torque).
